Mempool State - Bytes per Fee Level

The mempool consists of all transactions waiting to be confirmed by the Bitcoin network. This chart shows the current state of the mempool (as seen by our bitcoin nodes) organized by Fee Level. Each transaction’s ‘Fee Level’ is defined as the number of Satoshis per byte the transaction pays (bitcoin transactions vary in size depending on the characteristics of the transaction).

In order to maximize profits, miners typically give priority to transactions paying at a higher Fee Level. Blockchain.info Fee Level recommendations are shown above in blue and red and are available via our API.
